'While defending, your Tank was destroyed by a Persian Longswordsman.'
whoops
Wait till that happens with a spearman. Or a warrior
Anybody got a guide on how I'd go about winning by Cultural/Diplomatic/Scientific victory? Domination is straight forward, but when I try for the other ones I'm a little unsure what I should be focusing on.
Science Victory: You achieve a science victory by learning the necessary technologies to create all of the pieces of the space ship, then building the parts and moving them to your current capital (or building them there in the first place). Incidentally, space ship parts cannot be rushed or purchased. They must be constructed in a city.
Cultural Victory: To win a cultural victory, you must acquire five complete “branches” of social policies – that is, you must own all policies within six different branches. Once you’ve done that, the “Utopia Project” is unlocked. Construct that project and you win a cultural victory. You cannot rush or purchase this project; it must be constructed.
Diplomatic Victory: When a player learns the “Globalization” technology, he or she can construct the United Nations. Once that is constructed, a vote will be taken every few turns for the position of World Leader. If a leader gets enough votes to win the position, he or she immediately wins a diplomatic victory. The amount of votes needed to win a diplomatic victory depends upon the number of civilizations in play at the start of the game.
So if I was going for Science/Cultural/Diplomatic do I still need to build a military? Or is it possible to get other nations to protect me etc.?
Also say I have a city with a population of 5, is it worth improving more than 5 tiles? Do I get any benefit from this or is it just a waste of production/gold/etc?
The AI in Civ 5 is very aggressive. If you do not have a standing military, then you are asking for trouble. Even gandhi will probably invade you (6)
It takes a few turns to improve a tile, so you may want to plan ahead so that your extra population added won't be working unproductive tiles. Otherwise, there is no benefit or loss, AFAIK.
I have a few links to Guides/Walkthroughs:
